Unlike cutting taps, thread forming taps displace material rather than remove it, producing stronger threads with no chips to clear. This tap is manufactured from cobalt high-speed steel and finished with a titanium nitride (TiN) coating for extended tool life. It carries a modified bottoming chamfer with 2 to 2.5 chamfered threads, allowing threading close to the bottom of a blind hole. The class of fit is 6H with a D9 thread limit, meeting standard metric tolerance requirements for precision threaded fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for production and maintenance machining operations in metalworking shops, toolrooms, and manufacturing facilities. It is used to form M8x1.25 metric coarse internal threads in blind hole configurations. Approved material applications include alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. It is particularly well-suited for applications where chip evacuation is difficult or where thread strength is a priority over standard cut-tap methods.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCold-form thread generation eliminates chips, reducing clogging risk in blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction provides heat and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends tool life and reduces friction during forming operations\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2 to 2.5 threads) enables threading near the base of a blind hole\u003c\/li\u003e\n  \u003cli\u003e6H class of fit with D9 thread limit meets standard metric precision tolerances\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through feature required for this configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole thread forming in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum.

Ensure the workpiece is securely fixtured and the pilot hole diameter is correctly sized for thread forming before beginning the operation — consult OSG or standard thread forming drill charts for the appropriate hole size. Apply appropriate cutting fluid or tapping compound for the workpiece material to reduce tool wear and forming torque. Because this is a thread forming tap, do not use it as a direct replacement for a cut tap without verifying that the workpiece material is suitable for cold forming.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8x1.25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2 to 2.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.7165 inches (69.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5906 inches (15.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.1260 inches (28.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3180 inches (8.08 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.2380 inches (6.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 9.53 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT (14101)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1410104505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728656498994,"sku":"1410104505","price":42.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc27498a22f4aecb970819d50d88fcc0.jpg?v=1788694499","url":"https:\/\/voomisupply.com\/products\/osg-1410104505-thread-forming-tap-m8x1-25-metric-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
